A lot of Martinis were made by British contract arsenals like BSA (Birmingham Small Arms) in England. Occasionally you find Martinis made in India, although I have only seen a few, and they are very nice actions. And yes, hand-made Pakistani Martini actions show up occasionally, but surprisingly, they are actually stronger than the original British Martinis because the originals were made of cast iron. The smaller Martini actions were made of both cast iron and steel. I think a Martini in 303 would be fun, but I would not feed it a steady diet of it.
